IMPROVEMENT IN MASTER-WHEELS AND ADJUSTABLE TRAVERSE-PIN|0NSv 85c.

Specification forming part of Letters Patent No. [86,817, dated January30, 1877 application filed June 24, 1876.

ered to accommodate itself to the run of the master-wheel.

Figure 1 is a plan view of the master-wheel, pinion, andframe. Fig. 2 isa vertical seetionof the same, and Fig. 3 is a vertical view of thatportion of the wheel behind its di-- ameter.

A is the master-wheel; B, the cogs on both sides of same G, the flangeon its periphery, which flange will occupy the same position when eitherside of the wheel is up, and, being in the center of the periphery, willaid the castingby cooling, without springing the wheel; D, the bearingfor the pinion; E, the journal sustaining one end of the bearing D. Thisjournal, one end of which is in box N, and the other in a loop-endedbolt, passes through the bearing-beam. F, a bar across from girt G to H,and on which rests the end of bearing D; I, a screw-bolt through the barF and bearing D, with a nut, K, on its top; L, boxes in which the shaftof pinion M runs; 0, pinion running in the cogs on top of master-wheel.

To adjust the traverse-pinion, unscrew the nut on the top of screw I,and put under the hearing I); or take out a piece of packing, whichshould be placed under the end of bearing D in the first place, as maybe necessary to raise or lower the bearing D, and then screw up the nutagain, and the pinion is adjusted the right height, and the masterwheel,when the cogs are Worn by the drivingpinion, can be turned over and usedthe other side up.

I claim as new and as my invention 1. A master-wheel that can be usedeitherside up, with flange G on the outside of same, substantially asdescribed.

2. Traverse-pinion M, with adjustable bearing D,journal E, and screw I,all in combination, substantially as described.
